Ive been using factory unlocked Sony Xperias for a while (Z, ZL, Z Ultra)so never had this issue before, but I have an HTC One M8 coming and unfortunately its ATT branded, though I bought it from a private seller and not ATT themselves. Im also grandfathered into unlimited data for many years now, and with my Sonys can turn on mobile hotspot anytime and use my data with ATT none the wiser. Now Im assuming since I was dumb enough to buy an ATT phone, I will be told to contact ATT once I pop in my SIM and try to turn on mobile hotspot, is this correct? If so, will unlocking the phone resolve this issue? As of now ATT has no idea Ive bought this phone, nor did they ever even recognize my Sonys because they never sold them, but since this is an ATT M8, Im assuming theyll know immediately what Im using, identify my plan and lock me out. Im hoping I can get around that.
I also imagine since its an ATT phone it will have all sorts of abilities locked out and a lot of fluff added in. How can I get the features unlocked? Is there anyway to buy a carrier branded phone and get it to be similar to one that was bought factory unlocked from the beginning and never branded?
Any help and advice would be appreciated and TIA
